This week was nuts. We dealt with a service degradation due to issues between our CDN and data center edge network. On a long, holiday weekend it’s the last thing you want to deal with. There were eighteen action items to come out of the post mortem (which was long enough to merit an executive summary). This was one of the weirder issues I have ever seen as it involved three different companies and a few bad hops in a network path. I quoted Baruch Sadogursky two weeks ago, “Pain is instructional.” It definitely is! Meanwhile, my company, Bankrate, was getting acquired by Red Ventures for $1.24 billion.
Hopefully, the week ahead will be calmer. Doubtful given I’ll be in Atlanta on Monday, Denver on Tuesday, back in North Carolina on Sunday, and then back to Michigan later the following. Next week’s edition of DevOps’ish Weekly will be written right after the conclusion of GopherCon 2017! I’m attending GopherCon for the first time ever and am so thankful to have the opportunity to do so. If you’re there ask me for a DevOps’ish sticker.

Kubernetes Playground: This is so cool! Stand up a Kubernetes cluster with dashboard and everything in seconds to tinker with for up to four hours at a time.
Using a GPG key for SSH Authentication: PGP keys and SSH keys are different. It took me longer than I care to admit to understand this, given that the first StackExchange thread I found on the subject made it pretty clear that it’s not trivial to use one where you’re supposed to use the other.
How a 20-year old kernel feature helped USDS improve VA’s network: “this bug is fascinating because we started debugging Ruby on Rails from AWS and found the root cause in the NSOC Cisco Routers thanks to an ancient feature in the Linux kernel.”

Depression is not a sign of weakness: “What you don’t see is how terribly afraid I am of my own code, what if it’s bad? What if they laugh at me? What if they see how much I actually don’t know? Will I ever know enough?”
It’s 2017 and Mental Health is still an issue in the workplace: “We are in a knowledge economy. Our jobs require us to execute at peak mental performance. When an athlete is injured they sit on the bench and recover. Let’s get rid of the idea that somehow the brain is different.”
Finding, and Landing, the Right Job for You: Finding the right job is really hard. Take a look at my LinkedIn profile and you’ll see evidence of this fact. Finding the right balance of challenge and culture is very hard. These tips on navigating job hunting from Conor Delanbanque are a good start.
How to Interview Engineers: On the other side of job seeking is hiring. As a hiring manager, I am finding it very challenging to get people to open up during that initial phone call. I want details but not rambling, I want low ego but please tell me what you’re proud of. This how to is good and I especially think asking every candidate the same questions is very important.
